We use this method to measure the crude oil's viscosity for 3 states: Saturated oil's viscosity, viscosity above the bubble point and viscosity under the saturation pressure. Then the crude oil's viscosity is estimated by using KHAN model and roller ball method. After that using these data that include efficient conditions in measuring viscosity, the estimated viscosity by the presented method, a radial based neural method, is taught. This network is a kind of two layered artificial neural network that its stimulation function of hidden layer is Gaussian function and teaching algorithms are used to teach them. After teaching radial based neural network, results of experimental method and artificial intelligence are compared all together. Teaching this network, we are able to estimate crude oil's viscosity without using KHAN model and experimental conditions and under any other condition with acceptable accuracy. Results show that radial neural network has high capability of estimating crude oil saving in time and cost is another advantage of this investigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=viscosity" title="viscosity">viscosity</a>, <a href="https://publications.waset.org/abstracts/search?q=Iranian%20crude%20oil" title=" Iranian crude oil"> Iranian crude oil</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20based" title=" radial based"> radial based</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title=" neural network"> neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=roller%20ball%20method" title=" roller ball method"> roller ball method</a>, <a href="https://publications.waset.org/abstracts/search?q=KHAN%20model" title=" KHAN model "> KHAN model </a> </p> <a href="https://publications.waset.org/abstracts/29815/prediction-fluid-properties-of-iranian-oil-field-with-using-of-radial-based-neural-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29815.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">501</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Ranking Effective Factors on Strategic Planning to Achieve Organization Objectives in Fuzzy Multivariate Decision-Making Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elahe%20Memari">Elahe Memari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Aslizadeh"> Ahmad Aslizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Memari"> Ahmad Memari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today strategic planning is counted as the most important duties of senior directors in each organization.

One solution for managing such heterogeneous classes and addressing individual needs of students is to improve learner autonomy by using technological innovations such as blogging. The focus of this study is on investigating the effects of blogging on improving the quality of Iranian university students' writings. For this aim, twenty-six Iranian university students participated in the study. Students in the experimental group (n=13) were required to blog daily while the students in the control group (n=13) were asked to write a daily schedule using paper and pencil. After a 3-month period of instruction, the five last writings of the students from both groups were rated by two experienced raters. Also, students' attitudes toward the traditional method and blogging were surveyed using a questionnaire and a semi-structured interview. The research results showed evidences in favor of the students who used blogging in their writing program. Also, although students in the experimental group found blogging more demanding than the traditional method, they showed an overall positive attitude toward the use of blogging as a way of improving their writing skills. The findings of the study have implications for the incorporation of computer-assisted learning in L2 academic contexts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blogging" title="blogging">blogging</a>, <a href="https://publications.waset.org/abstracts/search?q=computer-assisted%20learning" title=" computer-assisted learning"> computer-assisted learning</a>, <a href="https://publications.waset.org/abstracts/search?q=paper%20and%20pencil" title=" paper and pencil"> paper and pencil</a>, <a href="https://publications.waset.org/abstracts/search?q=writing" title=" writing"> writing</a> </p> <a href="https://publications.waset.org/abstracts/31351/blogging-vs-paper-and-pencil-writing-evidences-from-an-iranian-academic-l2-setting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31351.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">402</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Preparation and Characterization of Nanocrystalline Cellulose from Acacia mangium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samira%20Gharehkhani">Samira Gharehkhani</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Farid%20Seyed%20Shirazi"> Seyed Farid Seyed Shirazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Gharehkhani"> Abdolreza Gharehkhani</a>, <a href="https://publications.waset.org/abstracts/search?q=Hooman%20Yarmand"> Hooman Yarmand</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Badarudin"> Ahmad Badarudin</a>, <a href="https://publications.waset.org/abstracts/search?q=Rushdan%20Ibrahim"> Rushdan Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Salim%20Newaz%20Kazi"> Salim Newaz Kazi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nanocrystalline cellulose (NCC) were prepared by acid hydrolysis and ultrasound treatment of bleached Acacia mangium fibers.

The aetiology remains unknown. Combination of at least three congenital anomalies of the following criteria is required for diagnosis: vertebral defects, anal atresia, cardiac anomalies, tracheo-esophageal fistula, renal anomalies, and limb defects. Case presentation: The first case was 1-day old male neonate with multiple congenital anomalies was bore from 28 years old mother. The mother had history of pregnancy with lymphocyte therapy. His anomalies included: defects in thoracic and lumbar vertebral, anal atresia, bilateral hydronephrosis, atrial septal defect, and lower limb abnormality. Other anomalies were cryptorchidism and nasal canal narrowing. The second case was born with 32 weeks gestational age from mother with history of pregnancy with lymphocyte therapy. He had thoracic vertebral defect, cardiac anomalies and renal defect. Conclusion: diagnosis based on clinical finding is VACTERL association. Early diagnosis is very important to investigation and treatment of other coexistence anomalies. VACTERL association in mothers with history of pregnancy with lymphocyte therapy has suggested possibly of relationship between VACTERL association and this method of pregnancy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anal%20atresia" title="anal atresia">anal atresia</a>, <a href="https://publications.waset.org/abstracts/search?q=tracheo-esophageal%20fistula" title=" tracheo-esophageal fistula"> tracheo-esophageal fistula</a>, <a href="https://publications.waset.org/abstracts/search?q=atrial%20septal%20defect" title=" atrial septal defect"> atrial septal defect</a>, <a href="https://publications.waset.org/abstracts/search?q=lymphocyte%20therapy" title=" lymphocyte therapy"> lymphocyte therapy</a> </p> <a href="https://publications.waset.org/abstracts/16267/two-cases-of-vacterl-association-in-pregnancy-with-lymphocyte-therapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16267.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">453</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Optimization of Flip Bucket Dents in Order to Reduce Scour Hole Depth (Plunge Pool) Using a Comprehensive Physical Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Majid%20Galoie">Majid Galoie</a>, <a href="https://publications.waset.org/abstracts/search?q=Khodadad%20Safavi"> Khodadad Safavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Karami%20Nejad"> Abdolreza Karami Nejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Roshan"> Reza Roshan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Scour downstream of a flip bucket in a plunge pool is caused by impingement of water jet force. In order to reduce this force and consequently reduce scour hole depth, flip buckets may equip by dents. The minimum scour hole depth might be occurred by optimization of dents (number, shape, placement) on flip buckets. In this study, a comprehensive physical model has been developed and various options for dents have been investigated. The experimental data for each dent option such as scour hole depth, angle of impingement jet, piezometric pressure in tail-water and jet trajectory have been measured for various discharges. Finally, the best option can be found by analysis of the experimental results which has been expressed in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scouring%20process" title="scouring process">scouring process</a>, <a href="https://publications.waset.org/abstracts/search?q=plunge%20pool" title=" plunge pool"> plunge pool</a>, <a href="https://publications.waset.org/abstracts/search?q=scour%20hole%20depth" title=" scour hole depth"> scour hole depth</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20model" title=" physical model"> physical model</a>, <a href="https://publications.waset.org/abstracts/search?q=flip%20bucket" title=" flip bucket "> flip bucket </a> </p> <a href="https://publications.waset.org/abstracts/20083/optimization-of-flip-bucket-dents-in-order-to-reduce-scour-hole-depth-plunge-pool-using-a-comprehensive-physical-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20083.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">394</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Identifying the Factors Influencing the Success of the Centers for Distance Knowledge Sharing in Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Noroozi%20Chakoli">Abdolreza Noroozi Chakoli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to examine the impact of five effective factors on the success of the managers of distance knowledge sharing centers in Iran.

However, their effects are not the same on each factor. The results show each of these factors is not only individually but also together affect the success of centers for distance knowledge sharing. Moreover, it was demonstrated that there is a correlation between these factors. The results of this study show what factors determine the success of the centers and their efficiency in distance knowledge sharing in Iran. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distance%20knowledge%20sharing%20centers" title="distance knowledge sharing centers">distance knowledge sharing centers</a>, <a href="https://publications.waset.org/abstracts/search?q=Iran%E2%80%99s%20knowledge%20centers" title=" Iran’s knowledge centers"> Iran’s knowledge centers</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20sharing%20centers" title=" knowledge sharing centers"> knowledge sharing centers</a>, <a href="https://publications.waset.org/abstracts/search?q=staff%20success" title=" staff success "> staff success </a> </p> <a href="https://publications.waset.org/abstracts/132416/identifying-the-factors-influencing-the-success-of-the-centers-for-distance-knowledge-sharing-in-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132416.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">145</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> ANA Negative but FANA Positive Patients with Clinical Symptoms of Rheumatic Disease: The Suggestion for Clinicians</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Esmaeilzadeh">Abdolreza Esmaeilzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehri%20Mirzaei"> Mehri Mirzaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Rheumatic disease is a chronic disease that causes pain, stiffness, swelling and limited motion and function of many joints. RA is the most common form of autoimmune arthritis, affecting more than 1.3 million Americans. Of these, about 75% are women. Materials and Methods: This study was formed due to the misconception about ANA test, which is frequently performed with methods based upon solid phase as ELISA. This experiment was conducted on 430 patients, with clinical symptoms that are likely affected with rheumatic diseases, simultaneously by means of ANA and FANA. Results: 36 cases (8.37%) of patients, despite positive ANA, have demonstrated negative results via Indirect Immunofluorescence Assay (IIFA), (false positive). 116 cases (27%) have demonstrated negative ANA results, by means of the ELISA technique, although they had positive IIFA results. Conclusion: Other advantages of IIFA are antibody titration and specific pattern detection that have the capability of distinguishing positive dsDNA results. According to the restrictions and false negative cases, in patients, IIFA test is highly recommended for these disease's diagnosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autoimmune%20disease" title="autoimmune disease">autoimmune disease</a>, <a href="https://publications.waset.org/abstracts/search?q=IIFA" title=" IIFA"> IIFA</a>, <a href="https://publications.waset.org/abstracts/search?q=EIA" title=" EIA"> EIA</a>, <a href="https://publications.waset.org/abstracts/search?q=rheumatic%20disease" title=" rheumatic disease"> rheumatic disease</a> </p> <a href="https://publications.waset.org/abstracts/23763/ana-negative-but-fana-positive-patients-with-clinical-symptoms-of-rheumatic-disease-the-suggestion-for-clinicians" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23763.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">499</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Serological Assay and Genotyping of Hepatitis C Virus in Infected Patients in Zanjan Province</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Esmaeilzadeh">Abdolreza Esmaeilzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Erfanmanesh"> Maryam Erfanmanesh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sousan%20Ghasemi"> Sousan Ghasemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzaneh%20Mohammadi"> Farzaneh Mohammadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Hepatitis C Virus (HCV), a public health problem, is an enveloped, single-stranded RNA virus and a member of the Hepacivirus genus of the Flaviviridae family. Liver cancer, cirrhosis, and end-stage liver are the outcomes of chronic infection with HCV. HCV isolates show significant heterogeneity in genetics around the world. Therefore, determining HCV genotypes is a vital step in determining prognosis and planning therapeutic strategies. Materials and Methods: Serum samples of 136 patients were collected and analyzed for anti-HCV antibodies using ELISA (The enzyme-linked immunosorbent assay) method. Then, positive samples were exposed to RT-PCR, which was performed under standard condition. Afterwards, they investigated for genotyping using allele-specific PCR (AS-PCR), and HCV genotype 2.0 line probe assay (LiPA). Results: Samples indicated 216 bp bands on 2% agarose gel. Analyses of the results demonstrated that the most dominant subtype was 3a with frequency of 38.26% in Zanjan Province followed by subtypes of 1b, 1a, 2, and 4 with frequencies of 25.73%, 22.05%, 5.14%, and 4.41%, respectively. The frequency of unknown HCV genotypes was 4.41%. Conclusions: According to the results, it was found that HCV high prevalent genotype in Zanjan is subtype 3a. Analysis of the results provides identification of certain HCV genotypes, and these valuable findings could affect the type and duration of the treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-HCV%20antibody" title="anti-HCV antibody">anti-HCV antibody</a>, <a href="https://publications.waset.org/abstracts/search?q=Hepatitis%20C%20Virus%20%28HCV%29" title=" Hepatitis C Virus (HCV)"> Hepatitis C Virus (HCV)</a>, <a href="https://publications.waset.org/abstracts/search?q=genotype" title=" genotype"> genotype</a>, <a href="https://publications.waset.org/abstracts/search?q=RT-PCR" title=" RT-PCR"> RT-PCR</a>, <a href="https://publications.waset.org/abstracts/search?q=AS-PCR" title=" AS-PCR "> AS-PCR </a> </p> <a href="https://publications.waset.org/abstracts/23761/serological-assay-and-genotyping-of-hepatitis-c-virus-in-infected-patients-in-zanjan-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23761.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">489</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> The Effect of Austempering Temperature on Anisotropy of TRIP Steel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Heidari%20Noosh%20Abad">Abdolreza Heidari Noosh Abad</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Abedi"> Amir Abedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Davood%20Mirahmadi%20khaki"> Davood Mirahmadi khaki </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The high strength and flexibility of TRIP steels are the major reasons for them being widely used in the automobile industry. Deep drawing is regarded as a common metal sheet manufacturing process is used extensively in the modern industry, particularly automobile industry. To investigate the potential of deep drawing characteristic of materials, steel sheet anisotropy is studied and expressed as R-Value. The TRIP steels have a multi-phase microstructure consisting typically of ferrite, bainite and retained austenite. The retained austenite appears to be the most effective phase in the microstructure of the TRIP steels. In the present research, Taguchi method has been employed to study investigates the effect of austempering temperature parameters on the anisotropy property of the TRIP steel. To achieve this purpose, a steel with chemical composition of 0.196C -1.42Si-1.41Mn, has been used and annealed at 810oC, and then austempered at 340-460oC for 3, 6, and 9 minutes. The results shows that the austempering temperature has a direct relationship with R-value, respectively. With increasing austempering temperature, residual austenite grain size increases as well as increased solubility, which increases the amount of R-value. According to the results of the Taguchi method, austempering temperature’s p-value less than 0.05 is due to effective on R-value. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20method" title="Taguchi method">Taguchi method</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20rolling" title=" hot rolling"> hot rolling</a>, <a href="https://publications.waset.org/abstracts/search?q=thermomechanical%20process" title=" thermomechanical process"> thermomechanical process</a>, <a href="https://publications.waset.org/abstracts/search?q=anisotropy" title=" anisotropy"> anisotropy</a>, <a href="https://publications.waset.org/abstracts/search?q=R-value" title=" R-value"> R-value</a> </p> <a href="https://publications.waset.org/abstracts/33313/the-effect-of-austempering-temperature-on-anisotropy-of-trip-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33313.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">326</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Design and Control of a Knee Rehabilitation Device Using an MR-Fluid Brake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mina%20Beheshti">Mina Beheshti</a>, <a href="https://publications.waset.org/abstracts/search?q=Vida%20Shams"> Vida Shams</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Esfandiari"> Mojtaba Esfandiari</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzaneh%20Abdollahi"> Farzaneh Abdollahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Ohadi"> Abdolreza Ohadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most of the people who survive a stroke need rehabilitation tools to regain their mobility. The core function of these devices is a brake actuator. The goal of this study is to design and control a magnetorheological brake which can be used as a rehabilitation tool. In fact, the fluid used in this brake is called magnetorheological fluid or MR that properties can change by variation of the magnetic field. The braking properties can be set as control by using this feature of the fluid. In this research, different MR brake designs are first introduced in each design, and the dimensions of the brake have been determined based on the required torque for foot movement. To calculate the brake dimensions, it is assumed that the shear stress distribution in the fluid is uniform and the fluid is in its saturated state. After designing the rehabilitation brake, the mathematical model of the healthy movement of a healthy person is extracted. Due to the nonlinear nature of the system and its variability, various adaptive controllers, neural networks, and robust have been implemented to estimate the parameters and control the system. After calculating torque and control current, the best type of controller in terms of error and control current has been selected. Finally, this controller is implemented on the experimental data of the patient's movements, and the control current is calculated to achieve the desired torque and motion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title="rehabilitation">rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetorheological%20fluid" title=" magnetorheological fluid"> magnetorheological fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=knee" title=" knee"> knee</a>, <a href="https://publications.waset.org/abstracts/search?q=brake" title=" brake"> brake</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20control" title=" adaptive control"> adaptive control</a>, <a href="https://publications.waset.org/abstracts/search?q=robust%20control" title=" robust control"> robust control</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network%20control" title=" neural network control"> neural network control</a>, <a href="https://publications.waset.org/abstracts/search?q=torque%20control" title=" torque control"> torque control</a> </p> <a href="https://publications.waset.org/abstracts/134338/design-and-control-of-a-knee-rehabilitation-device-using-an-mr-fluid-brake" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134338.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Sun Protection Factor (SPF) Determination of Sericin Cream and Niosomal Gel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farzad%20Doostishoar">Farzad Doostishoar</a>, <a href="https://publications.waset.org/abstracts/search?q=Abbas%20Pardakhty"> Abbas Pardakhty</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Hassanzadeh"> Abdolreza Hassanzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudeh%20salarpour"> Sudeh salarpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Sharif"> Elham Sharif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Sericin is a protein extracted from silk and has antioxidant, antimicrobial, antineoplastic, wound healing and moisturizing properties. Different cosmetic formulation of sericin is available in different countries such as Japan and the other south-eastern Asian countries. We formulated and evaluated the sunscreen properties of topical formulations of sericin by an in vitro method. Method: Niosomes composed of sorbitan palmitate (Span 40), polysorbate 40 (Tween 40) and cholesterol (300 µmol, 3.5:3.5:3 molar ratio) were prepared by film hydration technique. Sericin was dissolved in normal saline and the lipid hydration was carried out at 60°C and the niosomes were incorporated in a Carbomer gel base. A W/O cream was also prepared and the release of sericin was evaluated by using Franz diffusion cell. Particle size analysis, sericin encapsulation efficiency measurement, morphological studies and stability evaluation were done in niosomal formulations. SPF was calculated by using Transpore tape in vitro method for both formulations. Results: Niosomes had high stability during 6 months storage at 4-8°C. The mean volume diameter of niosomes was less than 7 µm which is ideal for sustained release of drugs in topical formulations. The SPF of niosomal gel was 25 and higher than sericin cream with a diffusion based release pattern of active material. Conclusion: Sericin can be successfully entrapped in niosomes with sustained release pattern and relatively high SPF. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sericin" title="sericin">sericin</a>, <a href="https://publications.waset.org/abstracts/search?q=niosomes" title=" niosomes"> niosomes</a>, <a href="https://publications.waset.org/abstracts/search?q=sun%20protection%20factor" title=" sun protection factor"> sun protection factor</a>, <a href="https://publications.waset.org/abstracts/search?q=cream" title=" cream"> cream</a>, <a href="https://publications.waset.org/abstracts/search?q=gel" title=" gel"> gel</a> </p> <a href="https://publications.waset.org/abstracts/25326/sun-protection-factor-spf-determination-of-sericin-cream-and-niosomal-gel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25326.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">500</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Conceptual Modeling of the Relationship between Project Management Practices and Knowledge Absorptive Capacity Using Interpretive Structural Modeling Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Abdolreza%20Mosavi">Seyed Abdolreza Mosavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Babakhan"> Alireza Babakhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Sadat%20Hoseinifard"> Elham Sadat Hoseinifard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Knowledge-based firms need to design mechanisms for continuous absorptive and creation of knowledge in order to ensure their survival in the competitive arena and to follow the path of development.

For this purpose, we have studied and reviewed the theoretical literature in the field of project management and absorptive knowledge capacity so as to clarify its dimensions and indexes. Then, using the ISM method, the relationship between them has been studied. To collect data, 21 questionnaires were distributed in project-oriented knowledge-based companies. The results of the ISM method analysis provide a model for the relationship between project management activities and knowledge absorptive capacity, which includes knowledge acquisition capacity, scope management, time management, cost management, quality management, human resource management, communications management, procurement management, risk management, stakeholders management and integration management.

Accordingly, effective corrosion inhibitors should be developed based on natural resources to mitigate sour corrosion in the oil and gas industry. Here, Arabic gum was employed as an eco-friendly precursor for the synthesis of innovative polyurethanes designed as highly efficient corrosion inhibitors for sour oilfield solutions. A comprehensive assessment, combining experimental and computational analyses, was conducted to evaluate the inhibitory performance of the inhibitor. Electrochemical measurements demonstrated that a concentration of 200 mM of the inhibitor offered substantial protection to mild steel against sour corrosion, yielding inhibition efficiencies of 98% and 95% at 25 ºC and 60 ºC, respectively. Additionally, the presence of the inhibitor led to a smoother steel surface, indicating the adsorption of polyurethane molecules onto the metal surface. X-ray photoelectron spectroscopy results further validated the chemical adsorption of the inhibitor on mild steel surfaces. Scanning Kelvin probe microscopy revealed a shift in the potential distribution of the steel surface towards negative values, indicating inhibitor adsorption and corrosion process inhibition. Molecular dynamic simulation indicated high adsorption energy values for the inhibitor, suggesting its spontaneous adsorption onto the Fe (110) surface. These findings underscore the potential of Arabic gum as a viable resource for the development of polyurethanes under mild conditions, serving as effective corrosion inhibitors for sour solutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20effect" title="environmental effect">environmental effect</a>, <a href="https://publications.waset.org/abstracts/search?q=Arabic%20gum" title=" Arabic gum"> Arabic gum</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion%20inhibitor" title=" corrosion inhibitor"> corrosion inhibitor</a>, <a href="https://publications.waset.org/abstracts/search?q=sour%20corrosion" title=" sour corrosion"> sour corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics%20simulation" title=" molecular dynamics simulation"> molecular dynamics simulation</a> </p> <a href="https://publications.waset.org/abstracts/177782/eco-friendly-polymeric-corrosion-inhibitor-for-sour-oilfield-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177782.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">62</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Deuterium Effect on the Growth of the Fungus Aspergillus Fumigatus and Candida Albicans</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farzad%20Doostishoar">Farzad Doostishoar</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Hasanzadeh"> Abdolreza Hasanzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Amin%20Ayatolahi%20Mousavi"> Seyed Amin Ayatolahi Mousavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction and Goals: Deuterium has different action from its isotopes hydrogen in chemical reactions and biochemical processes. It is not a significant difference in heavier atoms between the behavior of heavier isotope and the lighter One but for very lighter atoms it is significant . According to that most of the weight of all creatures body is water natural rate can be significant. In this article we want to study the effect of reduced deuterium on the fungus cell. If we saw the dependence of deuterium concentration of environment on the cells growth we can test this in invivo models too. Methods: First we measured deuterium concentration of the distillated water this analyze was operated by Arak’s heavy water company. Then the deuterium was diluted to ½ ¼ 1/8 1/16 by adding water free of deuterium for making media. In tree of samples the deuterium concentration was increased by adding D2O up to 10,50,100 times more concentrated. For candida albicans growth we used sabor medium and for aspergillus fomigatis growth we used sabor medium containing chloramphenicol. After culturing the funguses species we put the mediums for each species in the shaker incubator for 10 days in 25 centigrade. In different days and times the plates were studied morphologically and some microscopic characteristics were studied too. This experiments and cultures were repeated 3 times. Results: Statistical analyzes by paired-sample T test showed that aspergilus fomigatoos growth was decreased in concentration of 72 ppm( half deuterium concentration of negative control) significantly. In deuterium concentration reduction the growth reduce into the negative control significantly.

Give that pistachio tree is a tolerant type of tree to saline and alkaline soil and water conditions, but groundwater and irrigation water quality play important roles in main production this crop. For this purpose, 94 well water samples were taken from 25 wells and samples were analyzed. The results showed give that region’s geological, climatic characteristics, statistical analysis, and based on dominant cations and anions in well water samples (piper diagram); four main types of water were found: Na-Cl, K-Cl, Na-SO4, and K-SO4. It seems that most wells in terms of water quality (salinity and alkalinity) and based on Wilcox diagram have critical status. The analysis suggested that more than eighty-seven percentage of the well water samples have high values of EC that these values are higher than into critical limit EC value for irrigation water, which may be due to the sandy soils in this area. Most groundwater were relatively unsuitable for irrigation but it could be used by application of correct management such as removing and reducing the ion concentrations of Cl‾, SO42‾, Na+ and total hardness in groundwater and also the concentrated deep groundwater was required treatment to reduce the salinity and sodium hazard. Given that irrigation water quality in this area was relatively unsuitable for most agriculture production but pistachio tree was adapted to this area conditions. The integrated management of groundwater for irrigation is the way to solve water quality issues not only in Rafsanjan area, but also in other arid and semi-arid areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=groundwater%20quality" title="groundwater quality">groundwater quality</a>, <a href="https://publications.waset.org/abstracts/search?q=irrigation%20water%20quality" title=" irrigation water quality"> irrigation water quality</a>, <a href="https://publications.waset.org/abstracts/search?q=salinity" title=" salinity"> salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=alkalinity" title=" alkalinity"> alkalinity</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafsanjan%20plain" title=" Rafsanjan plain"> Rafsanjan plain</a>, <a href="https://publications.waset.org/abstracts/search?q=pistachio" title=" pistachio"> pistachio</a> </p> <a href="https://publications.waset.org/abstracts/10469/the-assessment-groundwater-geochemistry-of-some-wells-in-rafsanjan-plain-southeast-of-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10469.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">417</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Energy-Efficient Storage of Methane Using Biosurfactant in the Form of Clathrate Hydrate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Farhadian">Abdolreza Farhadian</a>, <a href="https://publications.waset.org/abstracts/search?q=Anh%20Phan"> Anh Phan</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Taheri%20Rizi"> Zahra Taheri Rizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Elaheh%20Sadeh"> Elaheh Sadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The utilization of solidified gas technology based on hydrates exhibits considerable promise for carbon capture, storage, and natural gas transportation applications. The pivotal factor impeding the industrial implementation of hydrates lies in the need for efficient and non-foaming promoters. In this study, a biosurfactant with sulfonate, amide, and carboxyl groups (BS) was synthesized as a methane hydrate formation promoter, replicating the chemical characteristics of amino acids and sodium dodecyl sulfate (SDS). The synthesis of BS was achieved using an eco-friendly and three-step process. The first two steps were solvent-free, while a water-isopropanol mixture was utilized in the final step. High-pressure autoclave experiments demonstrated a significant enhancement in methane hydrate formation kinetics with low BS concentrations. 50 ppm of BS yielded a maximum water-to-hydrate conversion of 66.9%, equivalent to a storage capacity of 119.9 v/v in distilled water. With increasing BS concentration to 500 ppm, the conversion degree and storage capacity reached 97% and 162.6 v/v, respectively. Molecular dynamic simulation revealed that BS molecules acted as collectors for methane molecules, augmenting hydrate growth rate and increasing the number of hydrate cavities. Additionally, BS demonstrated a biodegradability exceeding 60% within 28 days. Toxicity assessments confirmed BS's biocompatibility, with cell viability above 70% for skin and lung cells at concentrations up to 160 and 80 µg/mL, respectively. BS showed significant potential as an environmentally friendly alternative to synthetic surfactants like SDS for methane storage. These findings suggest that the synthesis of effective, such as BS, holds promise for diverse applications, including seawater desalination, carbon capture, and gas storage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solidified%20methane" title="solidified methane">solidified methane</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20storage" title=" gas storage"> gas storage</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20hydrates" title=" gas hydrates"> gas hydrates</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20surfactant" title=" green surfactant"> green surfactant</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20hydrate%20promoter" title=" gas hydrate promoter"> gas hydrate promoter</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20simulation" title=" computational simulation"> computational simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/195035/energy-efficient-storage-of-methane-using-biosurfactant-in-the-form-of-clathrate-hydrate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/195035.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Comparing the Efficacy of Minimally Supervised Home-Based and Closely Supervised Gym Based Exercise Programs on Weight Reduction and Insulin Resistance after Bariatric Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haleh%20Dadgostar">Haleh Dadgostar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Kaviani"> Sara Kaviani</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanieh%20Adib"> Hanieh Adib</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Mazaherinezhad"> Ali Mazaherinezhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Solaymani-Dodaran"> Masoud Solaymani-Dodaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Fahimeh%20Soheilipour"> Fahimeh Soheilipour</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Pazouki"> Abdolreza Pazouki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Objectives: Effectiveness of various exercise protocols in weight reduction after bariatric surgery has not been sufficiently explored in the literature. We compared the effect of minimally supervised home-based and closely supervised Gym based exercise programs on weight reduction and insulin resistance after bariatric surgery. Methods: Women undergoing gastric bypass surgery were invited to participate in an exercise program and were randomly allocated into two groups. They were either offered a minimally supervised home-based (MSHB) or closely supervised Gym-based (CSGB) exercise program. The CSGB protocol constitute two sessions per week of training under ACSM guidelines. In the MSHB protocol participants received a notebook containing a list of recommended aerobic and resistance exercises, a log to record their activity and a schedule of follow up phone calls and clinic visits. Both groups received a pedometer. We measured their weight, BMI, lipid profile, FBS, and insulin level at the baseline and after 20 weeks of exercise and were compared at the end of the study. Results: A total of 80 patients completed our study (MSHB=38 and CSGB=42). The baseline comparison showed that the two groups are similar. Using the ANCOVA method of analysis the mean change in BMI (covariate: BMI at the beginning of the study) was slightly better in CSGB compared with the MSHB (between-group mean difference: 3.33 (95%CI 4.718 to 1.943, F: 22.844 p < 0.001)). Conclusion: Our results showed that both MSHB and CSGB exercise methods are somewhat equally effective in improvement of studied factors in the two groups. With considerably lower costs of Minimally Supervised Home Based exercise programs, these methods should be considered when adequate funding are not available. <p
